Bearcats! (1971)

(Pilot) Mercenaries Johnny Reach and Hank Brackett cruise the American Southwest in 1914 in their Stutz Bearcat in search of action and adventure. They often take dangerous assignments for pay; their fee is usually a blank check, and after the mission, they just fill in whatever amount they think the job was worth.  In the opening film "Powderkeg" a Mexican bandit is about to be executed in the United States. So his brother takes over a train and holds the passengers as hostages unless his brother is released. Reach and Brackett to the rescue!
